Description

The javadoc describes the view persistence (.dat) file:

Locators persist membership information in a locatorXXXview.dat file. This file is used to recover information about the cluster when a locator starts if there are no other currently running locators. It allows the restarted locator to rejoin the cluster.

When this ticket is complete, the Running Geode Locator Processes page will mention the view persistence .dat file and explain its purpose. Also, the page will highlight the split-brain vulnerabilities (see #GEODE-9680) associated with missing or stale .dat files.
